Cerebral Manifestations of Alveolar Soft-Part Sarcoma

Abstract

Clinical, pathological, and radiological features of metastatic cerebral lesions resulting from alveolar soft-part sarcoma are presented. Angioarchitecture, scintiscans, and radiotherapeutic findings are discussed. The morphologically indolent nature of the lesion was documented by roentgenographic methods in one case. The unusual juxtaposition of the tumor cells to the endothelium seems responsible for the highly vascular appearance of the lesion on angiography, the frequency of hematogenous spread, and the grave, although delayed, prognosis.
